> - The ability to login to many platforms without needing to create an account on that specific platform (universal login as mentioned by others)

Dude, how come no one is talking about this instead of cryptocurrency and NFT FOMO bullshit? That's actually useful. When do we get that?

Is it actually useful?

It saves people from needing to create passwords for each service if they don't use a password manager while also eliminating SSO as a data collection mechanism for major internet companies. That's not nothing, but the entirety of this is achieved by signature based authentication, which has existed for years and years but has achieved basically zero adoption.

It is obviously useful, and indeed it could be implemented by readily available methods. If "Web3" was really about getting that done, making the adoption actually happen, I think I'd be a lot less inclined to think the whole thing is just hype-based scams.

Like IndieLogin/IndieAuth?

Isn’t this Google Login, which is already present in many online services?

Do you really want the same key to every door?

If the alternative is a different key for every door, yes. There's no reason it has to be strictly one key for everybody, but I don't need separate keys for most of the things I do online. I'm ok having my bank take one key and all my streaming services take a different one.
